We’re pretty happy that a 392 MW solar concentrating plant[1] is currently under construction in the Mojave Desert to supply enough juice to power 140,000 homes by 2013. But we’re even more excited to learn that BrightSource put out a request for proposals to architects and designers to come up with a better, lighter, stronger, faster (ok, not faster), power tower for their three solar energy plants. Our friends at RAFAA Architecture & Design[1] in Zurich sent us their proposal for two options that make use of prefabricated modular parts and have a strong focus on the total lifecycle impact. Not only does RAFAA want to build a better and more sustainable solar energy tower, but their designs are very easy on the eyes too!
